Audio analyzer optimized for production test

The APx515 from Audio Precision is two channel audio analyzer optimized for production test.

The analyzer has a typical THD+N of -106 dB, 24-bit FFTs, and 192k digital I/O. Within the company's APx Series, it sits just below the APx525, whose lower THD+N and chip-level connectivity options make it more appropriate for R&D.

A high speed test option enables the APx515 to make all the key audio measurements in less than three seconds. In stand-alone mode, test sequences are created by selecting from a list of common audio measurements and saving a single project file.

On an automated line, a master application can control the APx515 directly using the .NET API or APx LabVIEW driver. In either mode, the operator can control APx with a keyboard, footswitch or barcode scanner, or the system can be totally automated.

Graphical reports can be generated from MS Word templates, or data can exported to CSV or injected into a database.

All APx audio analyzers use the same software, enabling tests and results to be shared between vendors, R&D and production facilities anywhere in the world.

For example, a test engineer using an APx525 can create a production test sequence and email it to a contract manufacturer whose APx515 will run the project natively. Performing quality assurance on the production line, the APx515 operator can save a recording of the actual output of a device under test and email it (along with the 515’s settings) in a single project back to Engineering for further analysis.

Audio Precision has 14 models of analyzers across four families.

The APx515 costs $6200 in the US while the high speed test, advanced engineering measurements and acoustic response software options cost $500, $750, and $150 respectively or bundled together for $1000. The first unit is expeccted to ship in August, 2010.
